Nicholas Culpeper (18 October 1616 – 10 January 1654) was an English botanist, herbalist, physician and astrologer. His book The English Physitian (1652, later Complete Herbal, 1653 ff.) is a source of pharmaceutical and herbal lore of the time, and Astrological Judgement of Diseases from the Decumbiture of the Sick (1655) one of the most detailed works on medical astrology in Early Modern Europe. Culpeper catalogued hundreds of outdoor medicinal herbs. He scolded contemporaries for some of the methods they used in herbal medicine: "This not being pleasing, and less profitable to me, I consulted with my two brothers, Dr. Reason and Dr. Experience, and took a voyage to visit my mother Nature, by whose advice, together with the help of Dr. Diligence, I at last obtained my desire; and, being warned by Mr. Honesty, a stranger in our days, to publish it to the world, I have done it."
Culpeper came from a line of notabilities, including the courtier Thomas Culpeper, who was reputed to be a lover of Catherine Howard (also a distant relative), the fifth wife of Henry VIII.
